Film-based cellulose nitrate negatives are a unique class of objects that contain important information about life, historical buildings, and the natural landscapes past years. Increased sensitivity to storage conditions makes these highly flammable can lead irretrievable loss. In this regard, timely identification degradation process is necessary step towards further conservation restoration. This work studies possibility detecting based on artifact yellowing. A total 20 normal yellowed...
Multimetallic plasmonic systems usually have distinct advantages over monometallic nanoparticles due to the peculiarity of electronic structure appearing in advanced functionality systems, which is great importance a variety applications including catalysis and sensing. Despite several reported techniques, controllable synthesis multimetallic soft conditions still challenge. Here, mono-, bi- tri-metallic were successfully obtained as result single step laser-induced deposition approach from...
In this paper, we present a new methodology for creating 3D ordered porous nanocomposites based on anodic aluminum oxide template with polyaniline (PANI) and silver NPs. The approach includes in situ synthesis of templates nanomembranes laser-induced deposition (LID) Ag NPs directly the pore walls. proposed method allows formation structures high aspect ratio pores, topological ordering uniformity properties throughout sample, specific surface area. For developed structures, demonstrated...
The investigation of the temperature dependence FTIR spectrum n‐octanol in range from −150°C to 50°C is presented. observed changes registered spectra during gradual heating sample were analysed. structure transformation at phase transition solid liquid detected.
Surfaces functionalized with metal nanoparticles (NPs) are of great interest due to their wide potential applications in sensing, biomedicine, nanophotonics, etc. However, the precisely controllable decoration plasmonic requires sophisticated techniques that often multistep and complex. Here, we present a laser-induced deposition (LID) approach allowing for single-step surface NPs composition, morphology, spatial distribution. The formation Ag, Pt, mixed Ag-Pt on substrate was successfully...
Photographic artifacts carry important historical and cultural information. Materials used in photography at the turn of XIXth XXth centuries tend to degrade both over time if temperature humidity conditions storage are violated. In this connection, question arises determining safety degree monitoring condition photographic materials. Close attention should be paid materials that become flammable as a result decomposition. This class objects includes films based on cellulose nitrate. study...
We present an original type of model electrode system consisting bimetallic Au–Ag nanoparticles embedded in amorphous carbon matrix with extremely well-defined geometry parallel, straight, cylindrical macropores. The samples are prepared one step by direct laser deposition the metal/carbon composite onto inner walls a porous 'anodic' alumina serving as template. coating is homogeneous from top to bottom pores, and amount material deposited can be tuned duration procedure. As test system, we...
We present an efficient and easily implemented approach for creating stable electrocatalytically active nanocomposites based on polyaniline (PANI) with metal NPs. The combines in situ synthesis of followed by laser-induced deposition (LID) Ag, Pt, AgPt observed peculiarity LID PANI is the role substrate during formation multi-metallic nanoparticles (MNP). This allows us to solve problem losing catalytically particles from electrode's surface electrochemical use. synthesized PANI/Ag, PANI/Pt,...
Abstract The preparation of a highly ordered nanostructured transparent electrode based on combination nanosphere lithography and anodization is presented. size perfectly pore domains improved by an order magnitude with respect to the state art. concomitantly reduced density defect pores increases fraction that are in good electrical contact underlying conductive substrate. This improvement structural quality translates directly linearly into performance energy conversion devices built from...
The multi-analytical study of polyaniline samples obtained by in situ microsynthesis was performed.
In this work, we present an approach to the synthesis of hybrid multifunctional nanomaterials with pronounced functional properties (SERS, adsorption properties). One-step laser-induced deposition method was used synthesize Au-Ag@C nanoparticles. Physicochemical and obtained nanostructures were studied using various experimental techniques.
